nLEcTnmALLY-ooNTnoLmn comnrnnrron MECHANISM FOR LOCKS.

Application filed April 18, 1925. Serial No. 24,288.

This invention relates to new and useful improvements in looks and more particularly to an electrically operated combination mechanism tor locks. The main object of my invention is the provisionot an electrically controlled combination mechanism wherein a predetermined selective combination is actuated for releasing the locking member, said locking member being, automatically released in upon the completion of the selective combination. a v i, i

Another object of my invention isthe pro- ,vision of an electrically operated combination mechanism which employs, a selective 1-5 combination and wherein the actuating parts are automatically returned to their normal positions, should aperson operating the lock make an errorin carrying out the combination so that the person can again start at the beginning ofthe selective combination to properly operate the mechanism,

A further object of my invention is the provision of an electrically operated combination mechanism which may be applied to ca doorsot residences, vaults and other places where it is desired to normally retain the door in a locked position and wherein access canonly be gained through the door by an authorized person who is in possession of the 0 proper combination for actuating the lock.

, A still further object of the invention is the provision of an electrically operated a combination mechanism for locks which when applied to the door of a residence will :55 have the means for cont-rolling theselective combination located upon the exterior of the door so that a arty in possession of the proper combination may readily enter and has in connection therewith an ;audible signail to be sounded upon the interior of the residence and is further provided with a singleactuating mechanism whereby a party uponthe interior of the residence may actuate the lock independent of the selective mechanism. a

A still further object of my invention is the provision of a combination mechanism including electrically operated combination control cooperating with an electrically op- 50, crated' registering means whereby the selective combination may be carried-out through the actuation of the consecutive operation of the combination and registering mechanism a for completinglthe selective combination and automatically releasing the lock.

ith the above and other objectsin view,

ure 1,

'my invention consists in the novel features of construction and the combination and arrangement 01 parts to be hereinafter more tully described, pointed out in the claim and shown in theaccompanying drawings,

in which i line14lat of Figure 2,

Figures 10, 11 and 12 are detail perspective views of different parts of the device, and i Figure 13 is a diagrammaticview- In putting my invention into practice, it preferredwto have the operating mechanism supported ,upon the door casingand further, if desirable, may be located between the walls of a building soas to be entirely out of sight with means for gaining access to the same in case the device should need repairing, and the mainioperating mechanism is supported upon a bracket 1 which is proto the showing in Fig vided with. openings 2 whereby screws, bolts or the like may be used for retaining the bracketin position upon a suitable support.

The bracket has attached to its upperface an upright body plate 3which is securely attached to a vertically disposed lug 4: upon the upper face of the'bracket 1 and the longitu dlnal edges of the body plate are disposed at right-angles to the plate as shown at 5 to form acomplcte rigid, support for the body plate. pin 6 upon which is mounted a roe able member 7 having a curved portion 8 and an arm 9 extending from the end of the curved t llortion forming a guide for the rack 10. xtending laterally from the outer end of Thc body plate 3=carries a ivot the curved portion 8 and from the body of the member 7 are the spaced perforated cars 11 and slidably mounted within these ears is a guide rod 12, the upper end of which is connected to a lateral linger 13 carried by the rack 10 to properly guide the moven'ient of the rack and retain the same against one edge of the arm 9.

lviounted upon the body plate 3, adjacent the upper end thereof, is a solenoid 14, the pole 15 of which has its lower end movable through a guide 16 and mounted upon the pole 15 is a bell crank 17 one end of which projects through a slot 18 in the body plate 3 while the other end thereof is engaged with the teeth 19 on the rack 10. When the pole 15 is in its projected position, the end of the bell crank which extends through the slot 18, is engaged with a shoulder 20 on one side of the slot to normally maintain the arm 21 of the bell crank out of engagement with the teeth 19. As the pole 15 of the solenoid 14 moves into the solenoid, the arm 22 of the bell crank will ride ott 01 the shoulder 20 through the tension oitthe coil spring 23, causing the arm 21 to engage with the teeth 19 and reciprocate the rack 10 relative to the arm 9, the length of movement of the rack being equal to the distance between the teeth, and the rack is retained against returning movement by means of a Ushaped pawl 24 pivotally mounted upon the outstanding car 25 formed by stamping the same from the body plate 3. The arm 26 of the U-shaped member 24 rides over the teeth 19 and engages with the same to retain the rack 10 in a raised position so as to permit the arm 21 to be actuated as above. The rack 10 is normally retained in its lowermost position as shown in Figure 1 by means 01 a coil spring 27, the lower end of which is attached to the bracket 28 on the rockable member 7 while the upper end is attached to the linger 13 on the rack. I

The base plate is provided in the body thereof with an opening 29 behind. which is arrangedan insulated plate 30 having a plurality of longitiuliintlrows of spaced threaded openings'31. These openings in the plate 30 are preferably arranged longitudinally and in transverse alignment, as illustrated for receiving the pins 32, the pins being arranged in predetermined openings in accordance with the selective combination to be carried out. The solenoid 14 is electrically connected to a push button 33 so that when this button 33 is pressed inwardly to energize the solenoid 14 the pole 15 thereof is moved into the solenoid, moving the bell crank 17 laterally with the arm 21 in engagement with one of the teeth 19 on the rack 10, this operation moving the rack 10 over the plate 30, a distance equal to that from the bottom of the plate 30 to the first pin 32 in the'first longitudinal row so that the notch 34 in the rack will align with this pin. The rockable member 7 is then moved upon its pivot, moving the rack laterally so that the pin will pass through the notch 34 to the opposite side of the rack and permit the rack to drop downwardly again to its lowermost position.

Pivotally mounted upon the pin 35 andarranged upon the opposite face 01' the base plate 3 from the rockahle member 7 is anarm 36 carrying a pivot pin 37 at one end and a pivot pin 33 at the other end. Mounted upon the pivot pin 37 is a curved arm 39, having a linger 40 projecting at right-angles to the arm and extending through an open ing 41 in the base plate for engagement with the teeth formed on one edge of the rockable member 7.

A solenoid 43 is carried by the base plate 3 diagonally opposite the solenoid 14, the pole 44 of which is attached to the reciprocating arm 45, said arm having an angular guide plate 46 provided with a slot 47 which received the guide pin 48 carried by the base plate 3 and projecting upwardly from the guide plate 46 is a linger 49 having a hook 50 at its upper end. The lower end 01": the arm 45 has a horizontal plate 51 attached to the outer end of the pole 44 and has a lug 52 which extends through a slot 53 in the base plate 3 and engages one end of a pivoted bar 54 which is mounted on the pivot pin 38 which is carried by the arm 36. The arm 36 is retained in a normal. position by means of a coil spring 55 which is connected to one end of the arm as shown at 56 and to a lug 57 at the lower end of the base plate. The arm 36 is retained in a relatively normal position and is gOVGlliOd through the movement of the bar 54, one end of which engages the inner end of the pivot pin 37 while the other end is in direct contact with a lug 52 which bears against a shoulder 58 formed'in one sideot the slot 53.

In operating my improved combination mechanism, the push button 33 is to be actuated the proper number of times in accordance with a pro-determined selective combination. In the present instance, the combination is 1, 3, 7 and 9, thus the party desiring to open the door presses the registering button 33 inwardly to energize the solenoid 14, moving the pole 15 inwardly to thus impart a late at movement to the bell crank 17 which will cause the arm 21 to engage one of the teeth 19 on the rack 10 and move the rack upwardly a distance equal to the longitudi- 7 attached to the base plate 3. i

lowermost sition andtheypolelb drawn outwardly em the solenoid to a projected position, as shown in Figure l by meams-of the coil spring 23, the arm 26 of the U- shaped member 24 retainingthe, rack in a raised position; This arm 26 is retained in a nominal eng ing position with the teeth a-co1l spring (ill oneend of which is attached to the U-Eiilped-member' other is depressed seven times consecutively, operat- -ing the solenoid 14 the same number of 19 by means 24 above its pivot point while the After the button 59 has been pushedinwardiy incomplete the circuitto the solenoid-43, the poleq44thereof is drawn into the solenoid which will movethe Larm45 downwardly bringing the inclined shoulder stop 61 theneon mto engagement with the lug 152011 the u shlped nmnberfl so as to rockthe U'shaped member upon its pivot and disengage t earn: 26from the teeth 19. Thismovement will move the other arm 63 of the ru shaped member beneath the catch M on the pivoted arm 65 which it carries a weight 67 at its other end, thus retaining the arm 26 out of the path oifthe teeth 19 permit the rack todmpdownwards so as to 1y teits normal inoperativeposition,the pin being behind the upwardly extendingarm 68 of the rack. The button 33 isthen pressed mseeotively thnee times so as to impart three separate forward emovements of the rack 10 to bring the notch34 into alignment with the pin which is in the sec ond notch "from the right at which time the button 59 is pressed to carry out theoporation disclosed above, moving the rockable member 7 upon its pivot againstt'he tension of the spring 69. At this time, I wish to call attention to the faet that as the solenoid 43 and the pole 44mm inwardly to operate the reciprocatingarm 45, the downward movement of the plateol will cause the lug 52 to engage the "bar 54 which while attached to the pivot )38 will rock thearm 38 upon pivot moving the curved arm 39 upwardly so that the finger 40 will be engage with thenotehes 42 in the/lockable; member and rock the same upon its pi vot 6. At this time, I wish to call attention to the fact that the bar 54 is retained in anormal position by means of a spring coiled upon the pivot pin 38 with one end connected to the bar and the other end engaged beneath the stop arm 71 formed on the upper end of the curved arm 39. This spring 70 is of sufiicient tension to retain the bar 54 in a normal position relativc'to the arm 36 until the spring 55 has been placed under a certain degree of tension, thus upon the continued downward movement of the arm 45 will cause thelug 52 to rock the bar upon the pivot 38.

The edge of the rockable member 7 is provided at a point above the teeth 42 with a series of teeth 72 adapted to be alternately engaged by means oh! spring retained pawl 73, time at each operation of. the solenoid 43, the finger on the curved arm 39 will f rock the member? upon itspivot to pass one oi' the pins32 through the notch 34 of "the rack and as this is done, the pawl 73 engages one of thetceth "2 for retaining the roclmble member in its advanced position.

After the uppermost ill'lllb' onihe rack has passed the secondpin, the button 33 is times, raising the rack 10 nntil tl1e-notch34 therein is in alignment with the pin'rinthe third longitudinal row of openings at which time the solenoid 43 is again actuated as previously disclosed. Forthe fourth numborvof thecombination, the solenoid 14 is finger 77 and moves the contact arm 78:11pm the contact 79 onto thecontact 80.

In order to i provide means whereby the circuit between the battery 81 and the solenoid 43 will be broken, sufficiently, to permit the pole 44 to return to its normal outward position, a plate 82 is positioned upon the portion 83 ovenwhich are arm 78 rides while moving from the contact 179-io the contact 80, thus providing sufiicient break in the circuit to permit the pole 44 to move outwardly of thesolenoid' and return the arn-i- 45 to its normally raised position.

Thecontact :is connected to the automatic operating mechanism of the lock which has en previously disclosed in my co-pending application filed by me April 18, 1925, for loo struetureyand bearing Serial No. 24

$5, thus the lock is automatically actuated through thecontact oitwthe arm 78 with the contact point 80 which completes a circuit through the lock 84 and as soon as the arm 45 moves to its upward normal position the upper edge of the plate 46 will engage the-inner end of thearm 77 and move the arm 78 from the contact 80 back to the contact 79 beneath the plate 82, the raised portion 83 being curved on its' inner face to properly guide the arm 78 onto thecontact 79.

As the rockable member 7 moves laterally upon its pivot, during the actuation of the last combination number, the pawl 73will be positioned above the tapered shoulder 85 on the sliding bar 86 which is attached to oontact79at itsouter edge and has a raised 7 llll] the base plate 3 by the pivot pin which is arranged in the slot 87 in the bar, thus when the solenoid l3 is actuated to rock the arm 36 upon its pivot, the bar 54 will be operated beyond a certain pre-determined movement of the arm 36 so that the inner end thereof will move upwardly and engage the lug 88 on the upper end of the bar 86 which projects through an opening 89 in the base plate 3. this operation moving the bar 86 upwardly over the face of the base plate 3 and'cause the pawl 73 to ride over the shoulder 85 and be moved out oi the path of the teeth 72 so as to permit the rockable member 7 to return to its normal position. The rockable member 7 has .a projection 90 on its lower edge arranged in the path of the out-turned end 91 on the lower end of the bar 86 for engaging the same to return the bar to its normal lowered position after the rockablc member returns to its normal position so that the mechanism 'is' again ready for operation.

Should the operator become confused in pressing the button 33 the proper number of times so that the notclr3 l in the rack is out of alignment with the proper pin, and presses the button 59, thus energizing the solenoid 4-3, it will be noted that the limit of movement of the arm 36 is prevented.

through the engagement of the finger 4E0 with the teeth 42 on the rockable member,

thus permitting the bar 54 to continue in its movement and engage the lug 88 on the bar 86 to raise the bar so as to disengage the pawl 73 from the teeth 72 and permit the rockable member to return to its normal inoperative position so that the party will have to begin the operation over again; In actuating the rack 10. it will be noted that the arm 26 engages the teeth to retain the rack in its normal properly raised position while the arm 63 will engage behind the catch 64 of the arm'65 upon actuation of the lCClpl'OClliilllP; arm 45, thus retaining the arm 26 out of the path of the teeth while the rack drops to its normal position and striking the arm 65 to disengage the match 6% from the arm 63 so as to'again posit-ion the arm 26 on the face of the teeth 19.

It will be apparent tron'l-the above that any authorized person knowing the combination may quickly and readily operate the mecl'ianism to automatically release'the retaining loch forthedoor. It will also be apparent that a great number of selective combinations may be carried. out by arranging the pins 32 in various relative positions .withrespect to each other.- 7 v The bloclc92 which housesthe, contacts of 'which is connected in circuitwith thelock '84 so as'to release the lock lndependent :ot

the combination mechanism.

In selecting the various, combinations it will be apparent from the showing in Fi 1 that the lower set of horizontal openings which are indicated at 91 may be used as 0 in the combination.

lVhile I have shown and described the.

preferred form of my invention it will be obvious that various changes 'in the details of construction and in the proportions may be resorted to for. successfully carrying my invention into practice without sacrificing any of the novel features or" construction or departing from the scope of the appended claim.

Having thus described my invention, What I claim is: 1

In combination with anelectrically controlled lock, of an electrically controlled se lective mechanism, a pivoted switch, co operative means between the selective mechanism and switch whereby a predetermined movement of the selective mechanism and make and break a circuit through the electrically controlled lock, and means whereby to reset said mechanism uponcompletion of a selective combination upon actuation of said switch. 7

In testimony whereof I affix my signature.
